i cant put a dildo inside of me

So, as you can see from the title, i cant put a dildo in (im a virgin if that matters) I’ve tried using a vibrator and making myself aroused/orgasm beforehand. ive tried coconut oil. ive tried watching porn. I can fit like two fingers max inside of my vagina because 3 feels uncomfortable. it kinda burns whenever i try. has anyone had this problem????? do you have a fix/resolution???? thankssss
